This phase I trial studies the side effects and best dose of deoxyribonucleic acid (DNA)
vaccine therapy in treating patients with hepatitis C virus (HCV) infection that persists or
progresses over a long period of time. Vaccines made from DNA may help the body build an
effective immune response to kill cancer cells that express HCV infection.
